6. Salmon
Salmon is loaded with omega-3 fatty acids and has a number of health benefits. One of the potential downfalls, however, is that it may change the smell of your urine. This is because it contains vitamin B6. Keep in mind, this is a good thing, as the vitamin is an important part of a healthy diet. However, consuming large amounts of the vitamin may make your urine smell a little strange. Some people report having the same experience when taking vitamin B6 supplements.
